Computer not connecting to wifi

Hi,
Today my computer randomly won't connect to my WiFi anymore. I have never had any problems before. I have tried connecting and disconnecting with no change to the problem. It is not the networks problem as all other PC's in the house can connect to it. The computer cannot connect to any WiFi network.

Here are the specs/model:
Toshiba Satellite L850 (Laptop)
Windows 7
core i7, AMD radeon 7670m, 8 GB ram

If I click on troubleshoot it brings up a message saying:

There might be a problem with the driver for the Hamachi adapter
There might be a problem with the driver for the Local Area Connection Adapter
There might be a problem with the driver for the Wireless Network Connection Adapter

If I click on fix it will load for a bit but not change anything.

please help!!!
